We take comprehensive measures to acquire the expert knowledge. For example, we first define several criterions for selection of the experts in our study, which include that the expert should have worked in train operation field for many years and is capable of driving the trains with relatively good performance with guarantee of safety. Then, we derive a series of questionnaires for both experienced drivers and passengers. In addition, we install cameras in the locomotive cabs for observations of driving actions. The summarized expert knowledge can be divided into three parts. The first part is the conversion rules of operation modes, which restrict the operation mode switches to improve the riding comfort. In the second part, we define some operation rules in different operation mode. The third part focuses on a particular case in train operations to ensure that the speed of a train does not exceed the speed limits.
